• Construction screws

• Caulk or sealant

Contents:

• Galvanized box fan(1)

• Instruction manual(1)

Inspection:

After unpacking your exhaust fan, carefully inspect for any damage that may have occurred during transit. Inspect for loose, missing or damaged

parts. If there is physical damage to any parts of the fan, a freight claim must be filed with the carrier. Check to assure that all bolts, screws and

set screws are securely tightened and have not become loose during transit. Retighten as required. Rotate propeller by hand to assure it turns

freely.

General Safety Instructions

Danger: Before installing or servicing, always lock out and tag power source. Do not rely on a switch as the only means

of disconnecting power. Failure to disconnect power can result in fire, electrical shock or serious injury. Motor will restart without

warning after thermal protector trips. Do not touch an operating motor as it may be hot enough to cause injury. Do not place any body

parts or objects in fan or drive components while fan is connected to a power source.

Warning:

1. Read and follow all instructions, cautions, dangers and warnings. Failure to do so could result in personal injury, death or property damage.

2. Make sure the electrical power source conforms to the requirement of the fan(s) as well as local codes.

3. Electrical connections, installation and maintenance must be done by qualified electrical personnel in accordance with all applicable codes and

ordinances.

4. Unit must be adequately grounded.

5. To reduce the risk of fire or electrical shock, do not expose this fan to water.

6. Do not touch electrically live components.

7. Free rotation of the propeller is critical. It must not touch any part of the venturi, framework or drive components.

8. Assure that all power cords do not come in contact with any sharp edges, hot surfaces or chemicals. Immediately replace any damaged cords.

Caution: OSHA requires OSHA compliant guards when fan is installed within 7ft of the floor or working level.

Fan Installation

Caution: Before operating your new fan, check blade for proper torque, check all fasteners for tightness and assure

screens and/or shutters are securely in place.

For framing dimensions, refer to rough-in opening height and width shown in the specifications above.

Position the fan for desired airflow. Air will discharge on the side of the fan facing the propeller.

Assure the fan is fastened securely in the opening to avoid excess “rattling” or vibration using proper fasteners. Fasteners not included.

Refer to motor nameplate for wiring diagram.

Maintenance

Periodic maintenance schedules should be set to assure reliability and performance of the fan. This maintenance should included inspection of all

fasteners, propeller torque and proper cleaning of the complete fan assembly.

Check for excessive vibration while fan is running.

Periodically inspect and tighten all set screws and hardware.

Assure all mounting hardware, chains, etc. are properly secured.

Motors feature permanently sealed ball bearings and require no further lubrication.

The fan propeller should be periodically cleaned to assure proper balance and performance.

Grease pillow block bearings seasonally. Use caution not to apply too much grease as it may damage the seals.

Periodically check for proper belt alignment.
